Abstract

Container for storing two different substances, having a first compartment containing a liquid, a second compartment containing another liquid, a separating body which separates the two compartments, and a puncturing device comprising a tool which breaks the separating body when required and can be moved by hand by means of at least one transmitting part which transmits compression forces, such that the transmitting part is designed as a puncturing device comprising a press member having a press shank which is lengthened upon appliance of a lateral squeezing force onto the side walls of the compartment containing the puncturing device.

Claims

1. A container for separately packaging two different substances and for enabling mixing of said substances prior to dispensing thereof from said container, comprising:

a first compartment containing a first substance and a second compartment containing a second substance;

a frangible seal separating said first and second compartments;

a discharge port for enabling discharge from at least one of said compartments of a mixture of said substances; and

a puncturing device for breaking said frangible seal to establish a communication between said compartments; and

said puncturing device comprising a length extendable press shank and at a top end thereof a die with a sharp knife edge adjacent said frangible seal, said device being contained within one of said compartments in a guided manner to break said frangible seal upon application of a force against said press shank by laterally squeezing said compartment containing said puncturing device to extend the length of said press shank in the direction of said frangible seal, while said press shank is being supported by an inside wall of said compartment containing said functioning device, allowing said sharp knife edge to break said frangible seal.

2. The container according to claim 1, wherein said extendable press shank comprises an annular shank having spaced apart arched side walls being flexible to increase the length of said annular shank by laterally squeezing said side walls of said press shank together in forming a squeezed press shank having an elongated flattened annular shape.

3. The container according to claim 2, wherein said flexible design provides said annular shank with a shape memory.

4. The container according to claim 2, wherein a lower end of said annular shank in said elongated flattened annular shape is supported by an inside wall of a bottom face of said compartment containing said puncturing device.

5. The container according to claim 1, wherein said frangible seal comprises a film which is bonded in a sealing manner to the body forming said compartment containing said puncturing device.

6. The container according to claim 1, wherein said film comprises an aluminum foil.

7. The container according to claim 1, wherein said film is bonded in said sealing manner by inductive welding.

8. The container according to claim 1, wherein said two compartments have flanges to hold them together by at least one clip, each said at least one clip having an attachment selected from claws, snap-in and clamping connections, such that the at least one clip, when it has been pressed onto the flanges, is captively connected thereto.

9. The container according to claim 8, wherein said frangible seal lies between said flanges.

10. The container according to claim 1, wherein a bottom of said compartment containing said puncturing device includes a creasing line in order to yield when lateral walls of said compartment are squeezed together.
